Does the hood vent outside? Or does it throw air right above your face? I think we are supposed to change the filter in a range hood every so often but I’ve never done that even once in my life nor do I know anyone who has… I didn’t think of it until one time I was in the kitchen of a restaurant. Those are real hoods with a really good suction capacity.
